Question

when it is 12 noon in greenwich what is the local time at india(82°,30'E longitude)​

Answer 1

Answer:

So if it is 12 noon at Greenwich (0 degree), it would be 12:04 pm at 1 degree meridian and so on. In India, the standard meridian is 82-and-half degree. So the time difference between Greenwich and India is 82.5 x 4, which is 330 minutes (5 hours 30 minutes).
